Identification of True and False Aromatherapy Essential Oil

Carefully identify true and false essential oils

At present, essential oil occupies a place in the beauty and health care market. False is that a large number of low-quality, fake and shoddy essential oils are rushing into the market under the drive of interests. At present, most consumers are still at a loss about the ingredients and raw materials of essential oil, and lack a clear judgment about its cost performance. In this case, it is necessary to master some practical identification knowledge.

Method 1: Observe the product packaging.

I. Price

The flower yield, extraction method and oil yield of essential oil determine its price. The price of most pure essential oils is above 100 yuan, and it takes thousands of kilograms of rose petals to extract one kilogram of rose essential oil, so rose essential oil is very expensive; The essential oil extracted from the peel of citrus fruits such as sweet orange is relatively cheap because of its many raw materials and high oil yield.

The price of essential oil reflects its quality and nursing efficacy to a considerable extent. Don't try to buy essential oil with excellent efficacy at a low price. The essential oil with too low price is likely to be synthetic, with poor quality and even harmful to the body.

Second, specifications

The international standard specification of unilateral essential oil is 10ml, because unilateral essential oil is a high concentration of plant essence, and each use is measured by the number of drops, such as lavender, lemon, bergamot and so on. Of course, there are also small producing areas, especially limited, 5ml or 2ml of extremely expensive essential oils, such as roses and herbs. 20ml and above are rare.

Third, whether to mark the place of origin.

The quality and efficacy of essential oils extracted from plants growing in different regions will vary greatly. For example, the best varieties of lavender essential oil come from the southern highlands of France. Although lavender is also produced in other parts of France, it cannot be compared with lavender in the southern highlands in quality.

Fourthly, bottling.

1, pure essential oils

Essential oils must be packed in dark glass bottles to ensure quality, because light, high heat and high humidity will destroy the components of essential oils.

In order to avoid volatile deterioration, essential oils are usually kept in dark sealed small glass bottles, and the bottle caps also have special resistance to strong acids and alkalis. Pure plant essential oil, the purity should be indicated on the label. Bottled products with emitters are generally 3%~ 10% diluted essential oil.

At present, most of the bottling in pure essential oils is mainly dark green, dark blue, dark brown and amber glass bottles. Among them, dark green and dark blue glass bottles are more expensive because their shelf life is longer than that of dark brown and amber.

In addition, the bottling in pure essential oils must be accompanied by safety helmets and drippers, because the usage in pure essential oils is measured by the number of drips rather than milliliters.

2. No pure essential oils

No, the smell of pure essential oils is short and single, which may be pungent or cause headaches. Long-term inhalation may even cause harm to respiratory mucosa.

Instructions for the use of verbs (abbreviation for verb)

Most pure essential oils can't be applied directly to the skin. If the merchant introduces that it can be used directly on the skin, and it is also called pure essential oils, it is necessary to be wary of whether the merchant uses some base oils as essential oils.

Method 2: Observe the characteristics of essential oil.

First, the taste

The concentration of essential oil is very high, and it has a fragrance more than 70 times that of the original plant. The smell is natural, continuous and multi-layered. Essential oil contains hundreds of different molecules, which will make us feel the difference after the comprehensive action of the front taste, the middle taste and the back taste on the brain, with a long aftertaste. For example, citrus essential oil smells very fragrant, which can make people feel happy and easy to accept and like; Sandalwood essential oil has a deep smell and makes people feel very quiet.

Second, color.

Most essential oils are transparent and colorless, such as rosemary essential oil and rose essential oil. Some essential oils may also be light yellow, such as basil and frankincense, and sweet oranges are orange or golden yellow.

VI. Petroleum countries

Although essential oil is "oil", most essential oils are not greasy or greasy, but clear and transparent as water. We can drop 1 drop of essential oil on facial tissue or white paper to observe the state of essential oil. After the essential oil volatilizes, it generally does not leave oil stains. Some iron-containing essential oils may leave light yellow brown, and some citrus essential oils will leave light yellow traces.

Seven. pervade

1, pure essential oils

Because the molecules of plant essential oils are very small, they can penetrate into the skin quickly. Therefore, you can gently rub and massage the tested essential oil on the back of your hand (please dilute it before massaging it on the back of your hand when testing a single essential oil). The purer the essential oil, the faster it is absorbed, and it is not easy to produce a heavy and greasy feeling.

2. No pure essential oils

If it can't be completely absorbed after a long massage, or shiny oil components are left on the skin, it means that the essential oil is impure.
